Is it too early to try and naturally induce labor??

So I'm almost 37 weeks (36 wks+5) and I haven't had the slightest hint of labor. No Braxton hicks, no discharge, no nothing. So I'm fearing that they might have to medically induce me down the line which I don't want for a number of reasons. So I was wondering in it ok to go ahead and try the tricks to naturally start labor (walking, sex, eating pineapples lol)??? Or has anyone been in the situation before where they had no signs and out of the blue went into labor???
